Famed Chicago chef Charlie Trotter, whose namesake two-Michelin-starred restaurant closed in 2012, died Tuesday at 54, according to area reports.

Trotter was found unconscious at his Chicago home, NBC Chicago reported. His cause of death was not immediately known.

The chef and cookbook author might be best remembered for the long line of celebrity chefs that passed through his 25-year-old restaurant, including Grant Achatz of Alinea/Next, Giuseppe Tentori of Boka and Homaro Cantu of Moto.
